European foreword

This document (EN 1253-5:2017) has been prepared by Technical Committee CEN/TC 165

“Wastewater engineering”, the secretariat of which is held by DIN

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2017, and conflicting national standards shall

be withdrawn at the latest by August 2017

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights CEN shall not be held responsible for identifying any or all such patent rights

This document supersedes EN 1253-5:2003

This is the fifth part in EN 1253, a series of standards relating to different types of floor gullies, roof drains and access covers for drainage systems inside buildings The EN 1253 series under the main title

Gullies for buildings actually consists of the following parts:

— Part 1: Trapped floor gullies with a depth water seal of at least 50 mm;

— Part 2: Roof drains and floor gullies without trap;

— Part 3: Evaluation of conformity;

— Part 4: Access covers;

— Part 5: Gullies with light liquids closure

Since the latest versions of EN 1253-5 the most significant technical changes are the following:

a) introduction of the new standards on trapped floor gullies with a depth of water seal of at least

50 mm (EN 1253-1) and evaluation of conformity (EN 1253-3);

b) amendment of scope, classification, requirements as well as methods of marking

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom

1 Scope

This European Standard specifies requirements for the design, construction, performance, application and marking as well as test methods of factory made gullies with a light liquid closure for buildings Light liquid closures for buildings are applied to avoid uncontrolled discharge of light liquids into drainage systems in case of emergency

This European Standard does not apply to installations for separation of light liquids covered by

EN 858-1

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 1253-1:2015 and the following apply

3.1

gully with a light liquid closure

trapped floor gully with closure device which prevents the light liquid from entering the drainage system

3.2

light liquid closure

device which automatically closes the gully outlet when a certain level of light liquid is present

3.3

light liquid

liquid with a density not greater than 0,95 g/cm3 which is actually or practically insoluble in water and unsaponifiable

Note 1 to entry: Such liquids are, e.g petrol, diesel fuel, fuel oil

4 Types

Type A: Gully with an integrated light liquid closure with a flow rate in accordance with Table 1 for the unlimited use in gravity drainage systems

Type B: Gully with light liquid closure which is incorporated as an accessory, with a minimum flow rate given in Table 1, which may be reduced up to 30 % for use in gravity drainage systems

5 Materials

All material in contact with the light liquid and the wastewater shall be resistant to light liquids and to wastewater

6 Requirements

6.1 General

A gully with light liquid closure shall fulfil all requirements given in EN 1253-1, except for flow rates, and the following requirements given in 6.2 to 6.6

The manufacturer shall supply all the appropriate information concerning the use of the trapped gully with a light liquid closure, e.g handling, transport, temporary storage and instructions for installation, operation and maintenance

6.2 Inflow

The inflow shall be through the grating on the top of the gully

Inlets under the grating and behind the light liquid closure are not allowed

The light liquid closure shall be sufficiently protected against dust, dirt, inflow and others which could impair functioning

6.3 Security height

When the light liquid closure has closed the gully, there shall be a security distance between the sealing and the separating line between water and light liquid of ≥ 30 mm

7 Test methods

7.1 General

The gully shall, by means of the test methods in EN 1253-1, demonstrate the fulfilling the requirements given in EN 1253-1 and the following

7.2 Closing ability and tightness

After the flow rate test in accordance with EN 1253-1 add light liquid with a density corresponding to that indicated by the manufacturer ± 0,015 g/cm3 at 12 °C, slowly (≤0,1 l/s) into the gully, until the closure device closes, but at least up to the top of the grating Place a container under the pipe outlet, and determine after 1 h the amount of water and light liquid in the container

7.3 Security height

When the closure device has closed (see 7.2), measure by suitable methods the distance between the sealing and the separating line between water and light liquid

8 Marking

Gullies with a light liquid closure device and their components shall bear the following clear and durable markings, for example, cast on, by engraving, painting, stamping or labelling (including electronic recognition labelling) as indicated in Table 2:

a) EN 1253-5;

b) name and/or mark of the manufacturer;

c) period of manufacture (coded or not);

d) identification of independent certification body, where applicable;

e) identification of DN, load class and type
